p0420 code help! with freeze frame data
I have a 2002 toyota solara 4 cylinder
I recently got a p0420 mil light on my car. The car has no problems running, no difference at all actually and the light turns off by itself. It has came on and off twice and is still off.
After doing some research i heard it might be because the o2 sensors have never been changed since the life of the car. The car has 180,000 miles.
The reason i am asking if its the o2 sensors, even though the light is now off is because the gas mileage has gotten real bad.
here is the information:
P0420 (catalyst system efficiency below threshold (bank 1))
Freeze frame data
fuel sys 1...................CL
fuel sys 2...................NA
calc load (%)..............55.29
ECT(degreesC).............85
STFT B1 (%)................1.56
LTFT B1 (%)................3.91
Eng RPM....................2110
veh speed (km/h)..........54
IAT(degreesC)..............30
